Yes. All major bodies in the solar system have noticeable gravity. Ganymede and Callisto have surface gravities of 14% and 12% of Earth's gravity respectively.

Ganymede has 14.6 percent of the gravity of earth. Therefore, if an astronaut weighing 900 kg were on Ganymede, his gravitational pull would be the equivalent of 13.14 kg.
Because it is the biggest moon in the solar system. If you meant "moon" in your question, then your answer is here.
The physics of gravity dictate that two objects with mass push and pull on one another. They are both close to each other (relatively) and Jupiter has greater mass so its gravity keeps ganymede from pulling away from it. It is forced to go around Jupiter much like the our moon is forced to go around the earth.

Ganymede has 14.6 percent of the gravity of earth. Therefore, if an astronaut weighing 900 kg were on Ganymede, his gravitational pull would be the equivalent of 13.14 kg.
It is 1.428 ms-2 compared to 9.81 ms-2 on Earth.
It is 1.43 ms-2 compared to 9.81 ms-2 on earth.

I'm not 100% sure, but gravity is a relation of mass. On that basis I would say Ganymede a moon of Jupiter and the largest moon in the solar system
All matter causes gravity. Every planet will have a gravitational attraction. Certainly Earth, Mars, our Moon, and the Jovian moons Callisto and Ganymede will be walkable.
The surface gravity on Ganymede is 0.146 g, 14.6 % of the Earths and similar (a little lower) than our moons gravity of 0.165g. there is also no air resistance to slow the ball down. So if hit with the same force as on earth, a golf ball on Ganymede could probably reach 2-3 miles before landing, spending more than a minute in the air.
Although it would depend on your objective, Mars would generally be more suitable. Ganymede has far less gravity, far more ambient radiation (almost 8 rems a day), and is far colder.
